Which of the following statements accurately describes the role of mutations in evolution

• Mutations are the raw material for evolution, but most mutations do not result in evolution.

The palmarus longus tendon, pictured here, no longer serves a purpose in humans, but provides evidence of our species descendance from tree-dwelling ancestors. The palmarus longus tendon is an example of:

• a vestigial structure

• a homologous structure

• bipedalism

• convergent evolution

Q2. What are the types of structures that are similar in function but not in origin?

• analogous structures

• homologous structures

• vestigial structures

• none of the above

Many different groups of organisms have wings, even though they do not share a recent common ancestor. This is because they evolved in environments with similar selective pressures. Wings are an example of a(n) ______________ structure.

• vestigial

• analogous

• homologous
